Specification forming part of Letters Patent No. 203,701, dated May 14,1878; application filed April 1, 1878.

To all whom it may concern: I

Be it known that I, DAvLD F. BROWN, Sr., of Newton, in the county ofJasper and State of Iowa, have invented a Combined Vise, Wrench, andPinchers, of which the following is a specification:

My invention isa new hand tool adapted to be carried about and usedalternately as a vise, a wrench, and a pinchers for the various purposesfor which the three separate tools are commonly used, as hereinafterfully set forth.

Figure 1 of my drawing is a longitudinal side view, illustrating theconstruction of my invention and its operation as a hand-vise.

a is a four-sided straight metal bar, preferably made of wrought-iron.It may vary in size, as desired. It has an angular steel jawform top endand a curved pincher-jaw at its lower end.

b c is a bar corresponding in size and form with the bar a. It has ahinge-joint in its longitudinal center. To prevent it from bindingagainst the object to which the tool is clamped fast as a vise, I makethe movable jointed bar one-eighth of an inch thinner than the rigid bara.

d is a dowel-pin and guide, rigidly fixed to the lower portion of thepart b, and is designed to enter a corresponding perforation, f, in thestraight and rigid bar a, as indicated by dotted lines.

9 is a spring, secured between the two parallel mating portions of thevise, in any suitable way, to retain them apart when not held togetherby the operating-screw.

h is an operatingscrew, passed horizontally through the top portions ofthe parallel mating parts of the vise a b. The perforations throughwhich the screw h passes are threaded and form female screws, adapted toreceive the male screw h. I

h is an operating-screw, passing through a slot in the lower end of thehinged pincherjaw c, and into a female screw in the rigid matingpinoher-jaw formed on the lower end of the straight bar a. By means ofthe slot '5 in the hinged pincher-jaw c the hinged visejaw b is alwaysallowed to move parallel with its mate a, even when the pincher-jaws areclosed.

The tool thus illustrated is adapted for all the common uses of ahand-vise. By adjusting the jaws to fit a nut it can also beadvantageously used as a wrench where it can be revolved or partlyrevolved around the axis of the bolt upon which the nut is to beoperated.

The operatingscrews h and k may be rigidly fixed to the rigid bar a, andhave thumbnuts on their free ends; or they may have angular heads,adapting them to be operated by means of a key, common wrench, orspanner.

Fig. 2 illustrates my tool adjust-ed and applied as a pinchers, asrequired to hold abolt or any other object that can be clamped betweenits curved and serrated jaws. The slot 43 in the hinged jaw 0 allows thehinged jaw to assume various angles relative to the mating jaw, which isrigid.

Fig. 3 illustrates my tool secured as a vise to a fixed object.

m represents a fence-board or similar fixed and stationary object,adapted to hold my tool in a rigid manner while being used as astationary vise. n is a screw or clamping device of elbow form, thescrew end of which enters a threaded perforation formed in the side faceand upper portion of the rigid bar a.

By hanging the complete tool on the top edge of the fence-board, andthen pressing it laterally sufficient to make the hook engage the boardwhile the complete tool is revolved around the pivot formed by thescrew, the said screw is caused to pass deeper into orfarther throughthe bar, and thus cause the hook or elbow to clamp the fence-board andhold the vise firmly thereto,to be operated upon in the same manner thatstationary vises are used for various mechanical purposes.

I am aware that there is no novelty in the elbow-form screw n, and thatclamping devices having screws have been combined with a portable vise.

My combination of the device at with my combined vise, wrench, andpinchers is novel, and is advantageous in forming a stationary vise.

I claim v shown andideseribed, to be altematel'y Oper- As a new articleof manufacture, the hand ated as a ViSBfa wrench, and=a pinchers.
